Formation of a Photovoltaic Material from Precursor to Crystal

September 8, 2017

Lead halide perovskites have emerged as high-performance photovoltaic materials, with efficiencies skyrocketing from 3.8% to 22.1% in just seven years. At the Advanced Light Source, the ability to “print” thin films of this material from solution and observe changes in morphology during drying provides new insights into the relationship between device efficiency, perovskite crystallinity, and film morphology.
